TELEPHONIC-TELEGRAPHIO COMMUNICATION SYSTEM FOR RAILROAD-TRAINS.

Specification of Letters Patent.

Patented July 6, 1915.

Application filed February 24, 1915. Serial No. 10,218. a 1

To all whom it may concern:

Be it known that I, FELrcE ARENA, a sub-' telegraphic communication system for railroad trains.

The object of this invention is to provide a device whereby the engineer, conductor, motor man, passengers, or other person in charge can be incontinuous communication with all trains operating on the same track or upon other tracks, or with stations or places, whereby disasters can be averted and also whereby oflicials or employees can be notifiedin case of accident or to avert accident.

I will now proceed to describe my invention in detail, the novel features of which I will point out in the appended claims, reference being had to the accompanying drawing, forming part hereof, Wherein Figure 1 is a sectional view of one form of my invention; Fig. 2 is an enlarged section, the section being taken on a line 22 in Fig. 1; Fig. 3 is an enlarged plan view of the three throw switch which forms part of the apparatus.

As herein illustrated the device consists of a support 1 secured to a locomotive, car or the like, to which are secured a plurality of tubes 2, 3 and 4 by means of a plate 5 which engages a flange 6, one on each tube, bolts 7 being used to clamp the plate to the support. Each tube carries a collar 8 which is screwed up against the plate 5. The lower end of each tube is secured in a similar manner to a. channeled boot 9.

Each tube is provided with a vertically movable rod 10 normally pressed downwardly by a spring 11, one only being shown, the spring bearing against a collar 12 at its lower end and a bushing 13 at its upper end, the bushing 13 in the tube 3 being of insulating materal. The rods 10 will be preferably kept out, of contact with the platesy5 and support 1, should they be of metal.

The rod 10 in the tube 3 carries a brush contact 15 which gathers the current from a car, etc.

roads or railways, as explained in the fore conductor 16, the said conductor being charged with current conveyed thereto by a feed wire 17, the conductor being carried by a rail 18. I

Each rod 10 in the tubes 2 and 4 carries at its lower end a Wiper or cleaning brush 19 and a scraper 20. Y The brushes 19 and scrapers 20 keep the conductor 16 clean and free from ice or snow in the winter. Whichever brush and cleaner is in'use, depends upon the direction of travel of the train,

To raise and lower the rods 10, I provide each of the rods with an operating handle 21 pivoted to a support 22 at23, the support being provided with a ratchet segment 24 and the handle with a latch 25, only one handle 21 and segment 24 being shown.

The upper end of the rod 10 in the tube 3 carries a plurality of contacts 26, 27 and 28 and a switch arm 29 pivoted at 30 to the contact table 31. The contact 28, for instance, is connected to a telegraph instrument32, the contact 26 with a telephone and the contact 27 with a box having signals such as semaphore signals. The current is taken from the charged conductor 16 by the brush 15 and rod 10, thence to the switch 29. and thence to any instrument that the switch 29 may be in circuit with through the contacts 26, 27 and 28.

The engineer or other person can establish telephonic communication by moving the arm 29 to the contact 26 and depressing the brush 15 to contact with the conductor 16. To establish telegraphic communication, the arm 29 will be moved to the contact 28, and for ordinary signaling to the contact 27. The return circuit can be made through a rail 33 or other conducting means. The boot 9 protects the brushes 19 and contact brush 15 when said brushes are up.

The application of this system of telephony and telegraphy on all the trains, cars, locomotives, engines or motorcars of railgoing specification, may, of course, be more or less modified. For instance, the conductor may be aerial, upon or underground; it may be single or double, makinguse of the rails as return conductors; it may be continuous or interrupted; the contacts, instead of being brushes may be round disks; the telephonic or telegraphic places may be in- "ductor used as conne stalled in vehicle other than the 10cm motive, engine or motorcar and may also be multiple and accessible to the passengers or public, and lastly, it may be installed on all vehicles, other than railroad trains, or cars, following certain courses and connect ing at given places with a transmitting contion between the mov ingqand stationary points.

aving now described my invention, what I claim and desire to secure by Letters Patent is: 7

1. .A communicating system for locomotives, cars, or the like, consisting of a conducting rod carried by the moving element, means to raise or lower said rod, a conductor adjacent said conducting rod, a pivotal switch carried by said rod, a plurality of circuits adjacent said switch and arrangedto be connected therewith, and an independent signal device located in each of said circuits.

2.1%. communicating system for locomotives or other vehicles, consisting of a support, a plurality of tubes carried thereby, a

vertically movable rod within each tube, a cleaning device carried by two of said rods, at the lower ends thereof, a contact brush carried by the center rod, at the lower end thereof, a conductor adjacent said brushes,

means to raise and lower said rods independently, a pivotal switch carried by the center rod, a plurality of contacts adjacent said switch, and anindependent signal device in circuit with each contact. I

3. A communicating system for locomo-' tives or other vehicles, consisting of a support, a plurality of tubes carried thereby, a vertically movable rod within each tube, a cleaning device carried by two of said rods, at the lower ends thereof, a contact brush carried by the center rod, at the lower end thereof, a conductor adjacent said brushes, means to raise and lower said rods independently, a pivotal switch carried by the center rod, a plura 'ty of contacts adjacent said means? switch, an independent signal device in cir cuit with each contact, and a spring in each tube to normally force said rods downwardly.

'4. A; communicating system for locomotives or other vehicles, consisting of a support, a plurality of tubes carried thereby, a vertically movable rod within each tube, a cleaning device carried by two of said rods, at the lower ends thereof, a contact brush carried by the center rod, at the lower end thereof, a conductor adjacent said brushes, means to raise and lower said rods independently, a pivotal switch carried by the center rod, a plurality of contacts adjacent said switch, an independent signal device in circuit with each contact, a spring in each tube to normally force said rods downwardly, a lever to actuate each rod, a segment adjacent each lever, and a latch carried by each lever to engage said segment.

5. A communicating system for moving elements, consisting of a support, a plurality of tubes carried thereby, a channeled boot located at'the lower end of said tubes, a

.rod carried by each tube, a contact carried by the center rod at the lower end thereof, said boot being arranged to receive said contact, when said contact is up, a wiper carried by each of the other rods arranged to lie within said boot when not in use, a spring to normally force said rods downwardly, an operating lever for each rod, a segment for each lever, a latchcarried by each lever to engage said segment, a pivotal switch-arm carried by the center rod, a plurality of contacts adjacent thereto, and an independent signal device in circuit with each contact.
